ER4174-0002 | 4-channel analog output ±10 V or 0/4…20 mA, parameterisable, 16 bit

The ER4174 EtherCAT Box has four analog outputs which can be individually parameterised, so that they generate signals either in the -10…+10 V or the 0/4…20 mA range. The voltage or output current is supplied to the process level with a resolution of 15 bit (default), and is electrically isolated. The output scaling can be changed if required.

Ground potential for the four output channels is common with the 24 V DC supply. The analog actuators are supplied from the load voltage (freely selectable up to 30 V DC). The applied load voltage is available for actuator supply of further EtherCAT Box modules.

The EtherCAT Box modules with zinc die-cast housing are ready for use in harsh industrial and process environments. With the fully sealed design and metal surfaces the ER series is ideal for applications requiring enhanced load capacity and protection against weld spatter, for example.
